 *                 GNU LESSER GENERAL PUBLIC LICENSE
 *                      Version 3, 29 June 2007
 *
 * Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 * Everyone is permitted to copy and distribute verbatim copies
 * of this license document, but changing it is not allowed.
 *
 *
 *  This version of the GNU Lesser General Public License incorporates
 * the terms and conditions of version 3 of the GNU General Public
 * License, supplemented by the additional permissions listed below.
 *
 * 0. Additional Definitions.
 *
 *  As used herein, "this License" refers to version 3 of the GNU Lesser
 * General Public License, and the "GNU GPL" refers to version 3 of the GNU
 * General Public License.
 *
 *  "The Library" refers to a covered work governed by this License,
 * other than an Application or a Combined Work as defined below.
 *
 *  An "Application" is any work that makes use of an interface provided
 * by the Library, but which is not otherwise based on the Library.
 * Defining a subclass of a class defined by the Library is deemed a mode
 * of using an interface provided by the Library.
 *
 *  A "Combined Work" is a work produced by combining or linking an
 * Application with the Library.  The particular version of the Library
 * with which the Combined Work was made is also called the "Linked
 * Version".
 * 
 *  The "Minimal Corresponding Source" for a Combined Work means the
 * Corresponding Source for the Combined Work, excluding any source code
 * for portions of the Combined Work that, considered in isolation, are
 * based on the Application, and not on the Linked Version.
 * 
 *  The "Corresponding Application Code" for a Combined Work means the
 * object code and/or source code for the Application, including any data
 * and utility programs needed for reproducing the Combined Work from the
 * Application, but excluding the System Libraries of the Combined Work.
 * 
 *  1. Exception to Section 3 of the GNU GPL.
 * 
 *  You may convey a covered work under sections 3 and 4 of this License
 * without being bound by section 3 of the GNU GPL.
 * 
 *  2. Conveying Modified Versions.
 * 
 *  If you modify a copy of the Library, and, in your modifications, a
 * facility refers to a function or data to be supplied by an Application
 * that uses the facility (other than as an argument passed when the
 * facility is invoked), then you may convey a copy of the modified
 * version:
 * 
 *   a) under this License, provided that you make a good faith effort to
 *   ensure that, in the event an Application does not supply the
 *   function or data, the facility still operates, and performs
 *   whatever part of its purpose remains meaningful, or
 *
 *   b) under the GNU GPL, with none of the additional permissions of
 *   this License applicable to that copy.
 *
 *  3. Object Code Incorporating Material from Library Header Files.
 *
 *  The object code form of an Application may incorporate material from
 * a header file that is part of the Library.  You may convey such object
 * code under terms of your choice, provided that, if the incorporated
 * material is not limited to numerical parameters, data structure
 * layouts and accessors, or small macros, inline functions and templates
 * (ten or fewer lines in length), you do both of the following:
 * 
 *   a) Give prominent notice with each copy of the object code that the
 *   Library is used in it and that the Library and its use are
 *   covered by this License.
 *
 *   b) Accompany the object code with a copy of the GNU GPL and this license
 *   document.
 *
 *  4. Combined Works.
 *
 *  You may convey a Combined Work under terms of your choice that,
 * taken together, effectively do not restrict modification of the
 * portions of the Library contained in the Combined Work and reverse
 * engineering for debugging such modifications, if you also do each of
 * the following:
 * 
 *   a) Give prominent notice with each copy of the Combined Work that
 *   the Library is used in it and that the Library and its use are
 *   covered by this License.
 *
 *   b) Accompany the Combined Work with a copy of the GNU GPL and this license
 *   document.
 *
 *   c) For a Combined Work that displays copyright notices during
 *   execution, include the copyright notice for the Library among
 *   these notices, as well as a reference directing the user to the
 *   copies of the GNU GPL and this license document.
 *
 *   d) Do one of the following:
 *
 *       0) Convey the Minimal Corresponding Source under the terms of this
 *       License, and the Corresponding Application Code in a form
 *       suitable for, and under terms that permit, the user to
 *       recombine or relink the Application with a modified version of
 *       the Linked Version to produce a modified Combined Work, in the
 *       manner specified by section 6 of the GNU GPL for conveying
 *       Corresponding Source.
 *
 *       1) Use a suitable shared library mechanism for linking with the
 *       Library.  A suitable mechanism is one that (a) uses at run time
 *       a copy of the Library already present on the user's computer
 *       system, and (b) will operate properly with a modified version
 *       of the Library that is interface-compatible with the Linked
 *       Version.
 *
 *   e) Provide Installation Information, but only if you would otherwise
 *   be required to provide such information under section 6 of the
 *   GNU GPL, and only to the extent that such information is
 *   necessary to install and execute a modified version of the
 *   Combined Work produced by recombining or relinking the
 *   Application with a modified version of the Linked Version. (If
 *   you use option 4d0, the Installation Information must accompany
 *   the Minimal Corresponding Source and Corresponding Application
 *   Code. If you use option 4d1, you must provide the Installation
 *   Information in the manner specified by section 6 of the GNU GPL
 *   for conveying Corresponding Source.)
 *
 *  5. Combined Libraries.
 *
 *  You may place library facilities that are a work based on the
 * Library side by side in a single library together with other library
 * facilities that are not Applications and are not covered by this
 * License, and convey such a combined library under terms of your
 * choice, if you do both of the following:
 * 
 *   a) Accompany the combined library with a copy of the same work based
 *   on the Library, uncombined with any other library facilities,
 *   conveyed under the terms of this License.
 *
 *   b) Give prominent notice with the combined library that part of it
 *   is a work based on the Library, and explaining where to find the
 *   accompanying uncombined form of the same work.
 *
 *  6. Revised Versions of the GNU Lesser General Public License.
 *
 *  The Free Software Foundation may publish revised and/or new versions
 * of the GNU Lesser General Public License from time to time. Such new
 * versions will be similar in spirit to the present version, but may
 * differ in detail to address new problems or concerns.
 * 
 *  Each version is given a distinguishing version number. If the
 * Library as you received it specifies that a certain numbered version
 * of the GNU Lesser General Public License "or any later version"
 * applies to it, you have the option of following the terms and
 * conditions either of that published version or of any later version
 * published by the Free Software Foundation. If the Library as you
 * received it does not specify a version number of the GNU Lesser
 * General Public License, you may choose any version of the GNU Lesser
 * General Public License ever published by the Free Software Foundation.
 * 
 *  If the Library as you received it specifies that a proxy can decide
 * whether future versions of the GNU Lesser General Public License shall
 * apply, that proxy's public statement of acceptance of any version is
 * permanent authorization for you to choose that version for the
 * Library.
